3.6 964 engine computer issues. Where to go for ECU?

Everyone, as noted in my signature below I have a 1985 911 with a 1992 3.6 (Bill Verburgs old motor) in my car. Been running & driving for years just fine. Had a small engine fire (hose split and engine pad caught fire) thats now been fixed.

Engine has been cleaned up and all crispy wiring replaced but the shop ( a very good one) says that in the event they feel that the ECU wiring was damaged and caused issues to the computer itself. Engine runs but "hunts" and is not happy at lower speeds.

They feel that the ECU has a problem and its time to find another one or have this one overhauled/rebuilt. Suggestions? They are recommending "specialized ECU repair" but they are in Florida and I am in Phoenix.

Anyone have any recomendations? Thanks and am trying to get the car back on the road after two years sitting!! Before and after photos below!
